JAMES TVINANTS TALLMADGE, OF BOSTON, MASSACHUSETTS.

EXU DATHU N GAP.

SPECIFICATION forming part of Letters Fatent No. 599,872, dated February22', 1898.

Application filed November 1, 1897. Serial No. 657,100. (ModeL) To aZZwhom, it may concern;

Be it known that 1, JAMES Wnvxxrs TALL- MADGE, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and Commonwealth ofMassachusetts, have invented a new and useful Improvement in theManufacture of Exudation-Caps, of which the following is aspecification.

My invention relates to exudation-caps as patented to me October12,1897, No. 591,434; and it consists of mechanically joining the capand nozzle without detriment to either flexibility or porosity. Iaccomplish this object by means of the stiffener and holder deviceillustrated in the accompanying drawings, in which Figure 1 is anelevation of my exudationcap mounted upon the outlet portion of areceptacle. Fig. 2 is a sectional elevation of the same upon the line a:to in Fig. 1. Fig. 3 is a detail view of a porous nozzle provided withmy stiffener and holder. Fig. dis aview of said stiffener and holder.Fig. 5 is an edge view of said porous nozzle in its proper form forbeing adjusted in the apex of said cap, as shown in Fig. 1; and Fig. 6is a perspective view of amodified form of stiffener and holder withporous nozzle folded about it.

Similar letters refer to similar parts through out the several views.

D represents the outlet portion of a receptacle of any desired size,shape, or material.

A represents a flexible impenetrable cap, preferably of rubber.

B represents a compressible porous nozzle, (which is not susceptible ofhardening,) preferably of felt, provided with a stiffener and holder 0,preferably of aluminium wire, clasped around its middle, as shown inFig. 3. The porous material B is folded with said stiffener and holder 0at the line of flexure, as shown in Fig. 5. Thus formed, said nozzle Bis adjusted in apex of said cap A. The stifiener and holder 0 keeps apexof said cap A in the rectilinear form of said nozzle B, and the tensionof said cap Aholds said nozzle B in position. The lower portion. of saidcap A is adjusted to the diametrical exterior of the outlet portion ofreceptacle D, all as shown in Figs. 1 and 2.

A straight bar 0' may be employed as a stiffener and holder at thecrease-line in folded nozzle B, as shown in Fig. 6, instead of bandshown in Figs. 3, 4t, and 5.

Either form of stiffener and holder above described prevents cap A frombuckling, and being affixed at the neutral line of said nozzle B it doesnot interfere with the function of cap A or nozzle 13.

The flexible cap portion A acts as a hydraulic flexor, and the porousnozzle portion B acts as a combined stopper, conductor, and spreader,which will not exude until pressure is applied, no matter what positionreceptacle I) may be in.

This exudation-cap,being adjusted as above described to any suitablereceptacle containing the requisite fluid, forms a combination moresubstantial and is manufactured at much less cost than the vulcanizingor cementing process of unification shown in aforesaid patent to meOctober 12, 1897, No. 591,434, which is an excellent construction, butexpensive and difficult to manufacture on account of the felt charringby the heat required in vulcanizing. My present construction performsthe same function, and is used in precisely the same manner, by applying(like a brush) said nozzle B to the surface that requires moistening,the extrusion being controlled by operator using more or less pressure.

I claim 1. In an exudation cap, the combination of the flexible,impervious, openended cap, the porous, compressible nozzle, inserted inthe apex of the cap, and the stiffener and holder located in the captransversely of the nozzle and engaging the sides of said cap,substantially as described.

2. In an exudation-cap, the combination of the flexible, impervious,open-ended cap, the porous, compressible transverselyfolded nozzleinserted in the apex of the cap, and the stiffener and holder located inthe cap at the fold of the nozzle, and engaging the sides of the cap,substantially as described.

3. In an exudation-cap, the combination of the flexible, impervious,open-ended cap, the porous, compressible nozzle transversely-foldednozzle inserted in the apex of the cap, and the stiffener and holderlocated in the cap at the fold of the nozzle and extending around thesame, and engaging the sides of the cap, substantially as described.
